INTRODUCTION
If you have not yet arranged for professional installation, con-
tact your dealer, or call 1-866-347-3292, for information on
having your system installed by an authorized professional
installer.
This Satellite Dish Installation Guide Model: DW4000 Two-
Way provides information required to assemble your satellite
dish and establish contact with the satellite.
OTHER USEFUL GUIDES
The installation guide included with the software and indoor
equipment gives an overview of the entire installation process,
including the modem and software installation.
WHAT IS INCLUDED IN THE SATELLITE BROADBAND SYS-
TEM
The satellite broadband system consists of several major com-
ponents:
• The receive modem
• The transmit modem
• The satellite dish assembly that is installed outside
• Cables for connecting the modems and your computer
•Software
• This guide and the software and indoor equipment installa-
tion guide
This guide is intended for an installer experienced in perform-
ing the various installation tasks. The installer may be required
to:
• Use a power drill to drill holes into your house.
• Locate rafters or trusses and drill holes in the exact center of
them.
• Determine whether there are water pipes, electrical wiring, or
gas lines hidden in the walls near where you will be drilling.
• Route coaxial cable through the foundation wall, under
floors, and through interior walls.
• Ground the satellite dish and coaxial cable as recommended
in the National Electrical Code (published by the National
Fire Protection Association, Batterymarch Park, Quincy, MA
02269).
Contact your dealer, or call 1-866-347-3292, for information
on having your system installed by an authorized professional
installer.
INSTALLATION AND YOUR HOME
The Federal Communications Commission (FCC) has a rule
that generally forbids local governments and homeowners
associations from preventing installation of DBS dishes one
meter or smaller in size (in Alaska, the dish size limit does not
apply). For more information, please visit the FCC’s Web site
at www.fcc.gov. Use the site search engine to find the FCC
Fact Sheet on Placement of Antennas.
BASIC STEPS OF SATELLITE DISH INSTALLATION
Your installer will follow these basic steps:
1. Use a laptop computer to determine antenna pointing values
for your satellite dish
2. Choose an installation site
3. Select a mounting method
4. Install the mount
5. Assemble the satellite dish
6. Install the satellite dish on the mount
7. Run cable and ground wire to connect and ground the entire
assembly
8. Aim the satellite dish
9. Install the software on your computer and connect the satel-
lite modems to your computer
WARNING
Professional installation or service of your two-way
satellite dish is required by the Federal Communications
Commission because the radio transmits radio frequency
energy.
CAUTION
The two-way satellite dish must be installed in a location
or manner not readily accessible to childrenand at least 5
feet above ground level.
CAUTION
• This device emits radio frequency energy when in the
transmit mode.
• To avoid injury, do not place head or other body parts
between the feed horn and satellite dish when system
is operational.
• Unplug indoor power connection before performing
maintenance or adding upgrades to any satellite dish
components.

INSTALLING SOFTWARE AND LOCATING THE SATELLITE
Before you can install the satellite dish, you must select an installation site. Before you can select an installation site, you must deter-
mine the direction you will aim the satellite dish. The installer will use information on a laptop computer to determine the direction.
The satellite is located approximately 22,300 miles in geostationary orbit above the equator. The satellite travels above Earth’s equa-
tor from west to east at a speed matching that of Earth’s rotation, thus appearing stationary in relation to the Earth’s surface. To aim
the satellite dish at the satellite, you need to know the azimuth, elevation, and polarization angles. As shown in the figures below, you
set the satellite dish to the correct azimuth angle by turning it from side to side, and set the elevation by tilting the satellite dish up or
down. You set the polarization by rotating the satellite dish. The polarization setting rotates the satellite dish to the correct orientation
for your geographic location. This varies from one part of the country to another and is different for different satellites. Polarization
is positive in the eastern United States and negative in the western United States. Remember that it is important to pay attention to
positive (+) and negative (-) signs when recording and using antenna pointing values.
Before you install the satellite dish, the receive modem and software must be installed. To install the software, see the software and
indoor equipment installation guide for specific instructions. After you install the modem and software, run the software program. It
will take you to an Antenna Pointing screen, where you will be asked to enter your location or zip code. The software will provide the
azimuth, elevation, and polarization angles. Write them below. The pictures below will help you visualize these terms.

CHOOSING WHERE TO INSTALL THE SATELLITE DISH
TOOLS NEEDED
• Hand-held magnetic compass
• Angle finder or protractor
• Carpenter’s level or straight edge
Perform the following steps to select the best site to install the
satellite dish:
1. Go to the location where you plan to install the satellite
dish. This should be the shortest distance possible from
where you have installed your computer. If the total receive
cable length is greater than 150 feet see the cable specifica-
tions on page 7.
2. Face the south and hold the compass level so the needle can
rotate freely. When the needle stops rotating, it will be
pointing north. Carefully, so as not to disturb the needle,
rotate the body of the compass so that the 0° or Nmark
printed on the compass aligns with the painted end of the
needle. The compass is now aligned with magnetic north.
Note: Metal near the compass may affect your reading. If you are
standing near a metal structure, such as a shed or air conditioning
unit, move several feet away and repeat the measurement. Holding the
compass too close to a large metal belt buckle can have the same
effect.
3. Draw an imaginary line from the center of the compass to
the azimuth value you recorded on page 4. This is the direc-
tion to point the satellite dish. Use a rock or some other
object to mark the location where you are standing. Then
pick a landmark in the distance that aligns with the mag-
netic azimuth bearing, or mark the azimuth direction in
some other way.
.
CAUTION
• People can trip, fall into or otherwise bump into the sat-
ellite dish.
• Lacerations, bruises, or other impact injuries could
occur.
• Choose an installation site away from where people
are likely to work, ride, or play.

CHOOSING WHERE TO INSTALL THE SATELLITE DISH
4. Using the angle finder and a carpenter’s level or straight
edge, verify that there is an unobstructed line-of-sight
toward the satellite as shown in the diagram below. To do
this, align the level along the azimuth bearing. Then, using
the angle finder, lift the front end of the straight edge to cor-
respond to the elevation angle you recorded on page 4. Sight
along the straight edge to verify that there are no obstruc-
tions (such as buildings or trees) blocking the view. Take
into account future tree growth; if you install during the fall
or winter, account for spring and summer leaf growth. Also,
avoid installing the satellite dish next to electrical equip-
ment such as air-conditioning units, because they can cause
signal interference.

CABLE SPECIFICATIONS
Note: Coaxial cables with copper clad steel center conductor are not recommended.
Note: Do not use splitters.
Note: Line amplifiers are required for Receive cable runs of more than 150 ft.
Note: The grounding scheme you choose may affect your choice of cable; see “Overview of Grounding the Satellite System” on
page 29.
Use plenum grade cable only if the cable is to be run in plenum space which is carrying return air for the air circulation system, or
when local laws require it.
If the Receive cable run length is less than 150 ft., then no line amplifier is required. If the Receive cable run length is greater than
150 ft., but less than 300 ft., then install a line amplifier in the Receive cable only, at a minimum of 25 ft. and up to 30 ft. from the
LNB.
A line amplifier, if needed, can be installed only in the Receive cable, not in the Transmit cable.
Line amplifier specification: Channel Master 5113 IFD or equivalent.
Grounding and Cable Choice
Your choice of grounding scheme may affect your choice of cable; see “Overview of
Grounding the Satellite System” on page 29 for information about grounding. Note that
meeting the National Electrical Code grounding requirements is easier if you use RG-6 with
solid copper center conductor and quad shield. However, you can also meet the
requirements by using RG-6 with solid copper center conductor only and grounding the
mast as described in the Overview.
Recommended cable specifications for One-Way and Two-Way Systems
Cable length fromsatellite
dish to computer Type of cable to be used

Important: A higher grade of cable can be used for an installation where a lower grade is
specified. For example, an RG6 cable with solid copper center conductor and quad shield
can be used for installations where the cable length is less than 300 ft. Never use a lower
grade of cable than specified. Be sure to record the grade of the cable used for your
installation. The grade is printed on the cable every few feet. Never use a cable which
does not have the manufacturers name and its grade clearly printed on it!

SELECTING A MOUNTING OPTION
Based on the satellite dish installation site, decide on the best
surface for mounting your satellite dish. The base plate and
mast assembly that came with your satellite dish is called a uni-
versal mount. Some mounting options require only the univer-
sal mount. Other mounting options require that you also use
the two struts (called a brace kit) that came assembled with
your satellite dish kit. The struts slip over the mast and provide
additional support.
Note: Installers must:
• Follow the instructions in this manual precisely
• Install the satellite dish no higher than 30 feet above grade
• Install the satellite dish only on approved surfaces, and NOT on
any other surfaces
• If necessary, be able to locate wood members
• If necessary, install lag screws in the center of wood members
INSTALLING THE SATELLITE DISH ON A WOOD DECK POST
You can use the universal mount to install the satellite dish on a
6-inch x 6-inch Southern Pine wood deck post.
See “Installing The Mount on a Wooden Deck Post” on
page 10.
INSTALLING THE SATELLITE DISH ON TYPICAL WOOD
FRAMED ROOF CONSTRUCTION
You can use the universal mount and brace kit to install the sat-
ellite dish on typical wood framed roof construction.
See “Installing the Mount on a Wood Framed Roof” on
page 13.
CAUTION
• Before installing the universal mount brace kit, you
should obtain an analysis from a structural engineer to
confirm that the installation site is suitable for mounting
your satellite dish using the brace kit.
• Failure to ensure that the installation site is capable of
supporting the weight of the satellite dish could result
in personal injury or property damage.
CAUTION
The satellite dish should not be installed on a wood frame
roof unless the roof interior is unfinished so that
placement of lag screws can be verified and the interior
reinforced if necessary.
CAUTION
The satellite dish must be installed in a location or manner
not readily accessible to children and at least 5 feet above
ground level.

SELECTING A MOUNTING OPTION
INSTALLING THE SATELLITE DISH ON CONCRETE OR CON-
CRETE MASONRY WALLS
You can use the universal mount to install the satellite dish on
concrete masonry or concrete walls. The brace kit can also be
installed for greater stability, but is not required.
See “Installing the Mount on Concrete or Concrete
Masonry Walls” on page 18.
INSTALLING THE SATELLITE DISH ON A METAL POLE
You can install the satellite dish directly on an 9-foot metal
pole. If you choose this mount option you will not need the
universal mount or universal mount brace kit. Store them for
possible future use.
See “Installing the Mount Onto a Metal Pole” on page 20.

INSTALLING THE MOUNT ON A WOODEN DECKPOST
The satellite dish can be installed on a 6-inch x 6-inch Southern Pine wood deck support post. The post can be no more than 8 feet
tall. It must be securely attached at top and bottom. Posts made of other species of wood may be used as long as their material prop-
erties match or exceed those of Southern Pine. Posts made of other species of wood whose material properties do not match or
exceed those of Southern Pine require engineering evaluation and approval before being used. The satellite dish may not be installed
on an unsupported wooden post.

INSTALLING THE MAST ONTO A WOODEN DECK POST
INSTALLATION PROCEDURE
Note: for an installation to be successful, the mast must be plumb. Re-
plumb the mast whenever instructed to do so, and re-plumb it when-
ever you feel it is necessary.
1. Orient the universal mount so the square hole in the base
plate is at the top as in Figure 8 before installation.
2. Use a 1/2-inch socket wrench to loosen the adjustment nuts
and swing the mast so that it is oriented as in Figure 9.
3. Mark the centerline of the deck post.
4. With an assistant place the base plate on the centerline at the
spot you plan to install it (see Figure 8).
5. Loosen the pivot bolt nut and adjustment nuts and plumb the
mast in two perpendicular directions (see Figure 9). If you
successfully plumb the mast tighten the nuts and proceed to
step 6. If you cannot plumb the mast find another location to
install the satellite dish. Note: it is essential that the mast be
plumb. If you cannot make the mast plumb at this point, find
another installation site.
6. Mark the center of the base plate’s top center hole.
7. Drill a hole on the center mark in the manner described
below. Note: to avoid drilling too deeply, wrap a piece of
masking tape around the drill bit shank at the proper depth
so that you can see when you should stop drilling.
Drill a 1/8-inch pilot hole 2 inches deep.
Going into the pilot hole, drill a 1/4-inch hole 4 inches deep.
Going into the 1/4-inch hole, drill a 3/8-inch hole to a depth
equal to the unthreaded portion of the 3/8-inch x 4-inch lag
screw.
8. Fill the holes with silicone sealant and apply silicone sealant
to the entire back side of the base plate. Apply enough so
that it will press out around the edges when the plate is fas-
tened down (see Figure 10).
DANGER
•If the satellite dish contacts electric power lines, you
will be killed or seriously injured.
•Before starting the installation procedure, make sure
there are no power lines nearby.
CAUTION
•The satellite dish cannot be installed on an unsup-
ported wood post of any size.
•Install the satellite dish only on a wooden deck post.
•Install the satellite dish only as described in this man-
ual.

INSTALLING THE MAST ONTO A WOODEN DECK POST
9. Install a 3/8-inch washer on a 3/8-inch x 4-inch lag screw.
10. Use a wrench (preferably a ratchet) to screw the lag screw
into the top center hole of the base plate (see Figure 11).
You may need to swing the mast out of the way temporarily.
Tighten the screw snugly so that the base plate can barely
move.
Do not pound the lag screws into the post with a hammer or mallet.
Doing so may split the wood and render the post unusable.
11. Replumb the mast in two perpendicular directions as you
did in step 5. You may need to make adjustments to the mast
and/or the base plate.
12. Tighten the lag screw snugly so that the base cannot move.
13. Tighten the adjustment nuts.
14. Replumb the mast. (Tightening the nuts can move the mast
off plumb.) Note: the mast must be plumb before proceed-
ing.
15. Repeat step 6 and step 7 to drill holes for the top left center,
top right center, bottom left center, and bottom right center
holes. See Figure 11. Note: You must mark the center of all
screw holes accurately to keep the mast plumb. A Stanley
Jumbo Self Centering Nail Set or similar product will pro-
duce the best results. A #6 washer can also be used to guide
your pencil as it marks the hole center.
Note: the base plate must not move when you drill the holes.
16. Fill the holes with silicone sealant.
17. Install a 3/8-inch washer on each of the 3/8-inch x 4-inch
lag screws.
18. Use a 9/16-inch socket wrench to screw the lag screw into
the four holes. Tighten the screws loosely.
19. Re-plumb the mast and snug down the four screws firmly.
20. Loosen the mast adjustment nuts and swing the mast down
so you have access to the bottom center hole.
21. Repeat step 6 and step 7 to drill holes for the bottom center
hole.
Note: the base plate must not move when you drill the hole.
22. Fill the hole with silicone sealant.
23. Install a 3/8-inch washer on the final 3/8-inch x 4-inch lag
screw.
24. Use a 9/16-inch socket wrench to screw the lag screw into
the lower center hole. Do not tighten the screw fully.
25. Re-plumb the mast and snug down the lag screw.
26. Use a torque wrench with 1/2-inch socket to snug down the
mast adjustment nuts to 18 ft.-lbs. Confirm the mast is
plumb after torquing.
Note: The mast must be plumb before you can proceed. If you cannot
plumb the mast, repeat the installation or find another installation site.

INSTALLING THE MOUNT ON A WOOD FRAMED ROOF
You can install the satellite dish onto a wooden roof. You must use the brace kit. The minimum size for roof truss members is 2
inches x 4 inches. Roof rafters must be nominal 2x material (2x4, 2x6, etc.) Either size roof rafters or trusses must be16 to 24 inches
on center. The roof surface must consist of relatively thin, resilient materials, such as asphalt or composite shingles, sheet metal, or
similar materials, over wood sheathing with a thickness of 3/4 inch or less. Satellite dishes cannot be installed on flat roofs, slate
roofs, or Spanish tile roofing made of clay or other brittle materials. The roof pitch (or slope) must be between 3:12 and 12:12.
All center hole lag screws must be centered in the rafter or truss to which they are attached. For this reason, you must be able to
locate rafters and trusses and the center of rafters and trusses with a high degree of accuracy, which can be difficult to do. Home con-
struction varies a great deal. Construction styles, materials, and dimensions can all vary widely. In addition, stud finders give false
readings on a multi-layered surface, such as a roof. Also, you need experience in home construction to be able to determine the exact
location of rafters and trusses and their centers. The satellite dish should not be installed on a wood frame roof unless the interior of
the roof is unfinished so that placement of lag screws can be verified and the rafters or trusses reinforced if necessary.
If you do not have the knowledge and experience to accurately locate rafters and trusses and the center of rafters and trusses with a
high degree of reliability, you should contact a professional satellite dish installer for installation.
Large-timber roofs with frequent spacing of members are also permitted. These are constructed of wood members larger than the
nominal 2x sizes, and include post and beam structures with members from 4 inches x 4 inches and larger. The members cannot be
spaced more than 24 inches on center. Their physical properties must match or exceed those of Spruce-Pine-Fir #2.

INSTALLING THE MOUNT ON A WOOD FRAMED ROOF
INSTALLATION INSTRUCTIONS
Before you begin, make sure the rafters or trusses (called mem-
bers) in your house are located 16 to 24 inches on center.
Remember that 2 x 4 and 2 x 6 inch members are actually
1-1/2 inches thick. Also, because small movements by the base
plate are amplified at the end of the mast, re-plumb when
directed to do so.
Note: for an installation to be successful, the mast must be plumb. Re-
plumb the mast whenever instructed to do so, and re-plumb it when-
ever you feel it is necessary.
1. Orient the universal mount so the square hole in the base
plate is at the top as in Figure 13 before installation.
2. Loosen the adjustment nuts and swing the mast so that it is
oriented as in Figure 14.
3. Mark the centerline of the rafter or truss.
.
DANGER
•If the satellite dish contacts electric power lines, you
will be killed or seriously injured.
•Before starting the installation procedure, make sure
there are no power lines nearby.
CAUTION
•Rafters or trusses must be located 16 to 24 inches
apart on center, except for large-timber roofs, which
can be located no more than 24 inches apart on cen-
ter.
•The roof surface must consist of relatively thin, resilient
materials, such as asphalt or composite shingles,
sheet metal, or similar materials, over wood sheathing
with a thickness that must not exceed 3/4 inch.
•Satellite dishes cannot be installed on slate roofs or
Spanish tile roofing made of clay or other brittle materi-
als.
•The roof pitch (also called slope) must be between
3:12 and 12:12.
•The satellite dish cannot be installed on a flat roof.
•Center hole lag screws
must
be centered in the rafter
or truss.
•The satellite dish should not be installed on a wood
frame roof unless the interior is unfinished so that
placement of lag screws can be verified and the roof
reinforced if necessary.
•Install the satellite dish only as described in this man-
ual.
CAUTION
If you do not have the knowledge and experience to
accurately locate rafters or trusses and their centers with
a high degree of reliability, you should contact a
professional satellite dish installer for installation.

INSTALLING THE MAST ON A WOOD FRAMED ROOF
4. With an assistant place the base plate on the centerline at the
spot you plan to install it (see Figure 15).
5. Loosen the pivot bolt nut and adjustment nuts and plumb the
mast in two perpendicular directions (see Figure 16). If you
successfully plumb the mast, tighten the nuts and proceed to
step 6. If you cannot plumb the mast find another location to
install the satellite dish. Note: it is essential that the mast be
plumb. If you cannot make the mast plumb at this point, find
another installation site.
6. Mark the center of the base plate’s top center hole
(Figure 15).
7. Drill a hole on the center mark in the manner described
below. Note: to avoid drilling too deeply, wrap a piece of
masking tape around the drill bit shank at the appropriate
depth so that you can see when you should stop drilling.
Drill a 1/8-inch pilot hole 2 inches deep.
Going into the pilot hole, drill a 1/4-inch hole 4 inches deep.
Going into the 1/4-inch hole, drill a 3/8-inch hole to a depth
equal to the unthreaded portion of the 3/8-inch x 4-inch lag
screw.
Note: You must mark the center of all screw holes accurately to
keep the mast plumb. A Stanley Jumbo Self Centering Nail Set or
similar product will produce the best results. A #6 washer can
also be used to guide your pencil as it marks the hole center
8. Apply silicone sealant in the hole and to the entire back side
of the base plate. Apply enough so that it will press out
around the edges when the plate is fastened down.
9. Install a 3/8-inch washer on a 3/8-inch x 4-inch lag screw.
10. Use a 9/16-inch socket wrench to screw the lag screw into
the top center hole of the base plate (see Figure 15). You
may need to swing the mast out of the way temporarily.
Tighten the screw snugly so the base plate can barely move.
Note: Do not pound the lag screws into therafter or truss with a ham-
mer or mallet. Doing so may split the wood and render the rafter or
truss unusable.
11. Replumb the mast in two perpendicular directions as you
did in step 5. You may need to make adjustments to the mast
and/or the base plate. If you adjust the base plate, do not
move the center of the bottom center hole off the centerline
more than 1/16-inch.
12. Tighten the screw snugly so that the base plate cannot move.
13. Tighten the adjustment nuts.
14. Replumb the mast. (Tightening the nuts can move the mast
off plumb.) Note: the mast must be plumb before proceed-
ing.
15. Repeat step 6 and step 7 to drill holes for the bottom center
hole.
Note: the base plate must not move when you drill the hole.
16. Fill the hole with silicone sealant.

INSTALLING THE MOUNT ON A WOOD FRAME ROOF
17. Install a 3/8-inch washer on the 3/8-inch x 4-inch lag screw.
18. Use a 9/16-inch socket wrench to screw the lag screw into
the lower center hole. Do not tighten the screw fully.
19. Re-plumb the mast and snug down the lag screw.
20. Use a torque wrench with 1/2-inch socket to torque the mast
adjustment nuts to 18 ft.-lbs. Confirm the mast is plumb
after torquing. Note: the mast must be plumb before you can
proceed. If you cannot plumb the mast, repeat the installation or
find another installation site.
21. Adjusting the drilling depth for the 3/8-inch by 2-inch lag
screws, repeat step 6 and step 7 to drill holes for the four
cornerholes. See Figure 15.
Note: the base plate must not move when you drill the holes.
22. Fill the holes with silicone sealant.
23. Install a 3/8-inch washer on each of the 3/8-inch x 2-inch
lag screws.
24. Use a 9/16 socket wrench to screw the lag screws into the
four holes. Note: do not overtighten the screws. You may
strip the screw threads.
25. Re-plumb the mast and snug down the four screws firmly.
INSTALLING THE BRACE KIT
1. Slip the short 18-inch strut collar onto the mast as shown in
Figure 17.
2. Secure the collar to the mast by using a 7/16-inch socket
wrench to tighten the Nylock nut installed on the bolt.
3. Position the strut mounting plate below the mast and base
plate so the two screw holes are exactly in line vertically
with the mast base plate center holes (see Figure 17).
4. Mark the center of the bottom mounting plate screw hole
(see Figure 18).
5. Drill a hole on the center mark in the manner described
below. Note: to avoid drilling too deeply, wrap a piece of
masking tape around the drill bit shank at the appropriate
depth so that you can see when you should stop drilling.
Drill a 5/32-inch hole 4 inches deep.
Going into the 5/32-inch hole, drill a 1/4-inch hole to a
depth equal to the unthreaded portion of the 1/4-inch x 4-
inch lag screw.
6. Fill the holes with silicone sealant, and apply silicone seal-
ant to the bottom of the mounting plate.
7. Install a 1/4-inch washer on the 1/4-inch x 4-inch lag screw.
8. Use a 7/16-inch socket wrench to screw the lag screws into
the mounting plate hole.
Note: do not pound the lag screws into the rafter or truss with a ham-
mer or mallet. Doing so may split the wood and damage it.
